At 9pm the 22nd Battalion was relieved by the 21st Battalion who two nights later were raided by the Germans after a heavy Minnenwerfer barrage. The Battalion spent the next eight days in reserve with B, C, & D Companies at the Catacombs and A Coy plus Battalion HQ at Red Lodge, though every night spent working around the front line posts. The accommodation at the Catacombs ‘underground city’ was very comfortable and offered a good nights rest.
